ATTO R N EY Patented Feb. 5, 1946 WALL COVERING Ambrose W. Herbes, Jackson Heights, N. Y., as-

signor to The Ruberoid 00., New York, N. I, a corporation of New Jersey Application June 18,1945, Serial No. 600,049 4 Claims. (Cl. 2 0-5) This invention relates to a wall covering, and more particularly to an outer wall covering or weather-boarding formed of asbestos-cement siding elements.

One of the objects of the invention is to provide an outer wall covering of asbestos-cement boards that will simulate the appearance of a clapboard siding.

Another object is to provide a covering of asbestos-cement boards that will have a heavy or accentuated shadow-line to give an illusory effect of greater thickness of the covering elements.

A further object is to provide a weather and waterproof covering that will eflectively shed rain water.

A still further object is to provide a covering 4 that is inexpensive, durable, and easy to apply.

It is also an object of the invention to provide an outer wall construction that will permit breathing," that is to say it will allow moisture and water to' escape, thus eliminating sweating of the inner walls and thereby preventing paint peeling, wall paper discoloration, and damage from rot. v

Other objects and advantages of the invention will appear from the following description thereof, reference being had to the accompanying drawing in which:

Figure l is a front elevation, partly broken, of a section of a wall covering embodying the invention; and

Fig. 2 is a cross-sectional view takenon the line 2-2 of Fi 1.

The wall structure comprises the usual studding iii and sheathing I I, which latter may be of wood, composition board, or any other suitable material.

The covering elements i2 consist of fiat boards of asbestos-cement, or the like, of uniform thickness throughout and of greater length than width. Usually the boards are made in lengths of 4, 6 or 8 feet by 6, 8 or 10 inches in width, and about inch thick although these dimensions may be varied.

Beginning from the ground up, battens or laths l3 of wood or the like are fastened by nails It to the sheathing in horizontal rows. The battens are preferably slightly thicker than the siding elements, being usually about A to /2 inch thick. The several rows of battens are spaced apart uniformly at intervals somewhat less than the width of a siding element E2.

The siding elements of each course are applied with their upper edges l butting against the lower face of the battens of the next upper row and they are fastened to the sheathing by nails applied,

.ments applied in courses to said siding elements being of uniform thickness it. The lower edges ll of the siding elements bear on and overhang the battens of the next lower row. This effects the desired cent and overlap to simulate clapboard and conceals the nail heads.

On reference to Fig. 2 it will be seen that the lower edges of the siding elements of each course are spaced slightly outward, as at l8, from the upper edges of the elements of the next lower course. This not only permits of breathing" but also serves to cast a heavy shadow-line, represented by the shading as, that accentuates the apparent thickness of thesiding elements. The asbestos-cement siding elements are substantially impervious to moisture but by reason of the relative porosity of the battens and the space between the upper edges of the siding elements of one course and the overhang of the next upper course escape of moisture and vapor from the interior of the structure is permitted; Furthermore, it will be observed that air spaces 26 are formed between the sheathing l I and each course of siding elements. that increase the installation efficiency of the covering.

While the several rows of battens may be secured in place before the siding elements are the usual practice is to start from the base and to amx the battens of each row after the battens and the siding elements of the course below have been applied.

Strips M of asphalt saturated felt may be applied under the butting vends of the siding elements of each course to waterproof the joints.

What I claim is:

1. An outer wall structure comprising a sheathing and a covering of asbestos-cement siding elements applied in courses to simulate clapboard, said siding elements being of uniform thickness and of greater length than width, battens secured to the sheathing in horizontal rows at intervals slightly less than the width of a siding element, the siding elements of each course having their upper edges butting against the battens of the next upper row and having their lower edges resting directly on and overhanging the battens of the immediate lower row.

2. An outer wall structure comprising a sheathing and a covering of asbestos-cement siding eleand ofg'reater length than width, battens secured to the sheathing in horizontal rows at intervals slightly less than the width of a siding element, said battens being slightly thicker than the thickness of a siding element, the siding. elements of simulate clapboard,

each course having their upper edges butting against the battens of the next upper row and having their lower edges resting directly on and overhanging the battens of the immediate lower row.

3. An outer wall structure comprising a sheathing and a covering of fibro-cement siding elements applied in courses, battens ecured to the sheathing in horizontal rows, the siding elements of each course having their upper edges secured to the sheathing adjacent to one row of battens and having theirlower edges resting directly on the next lower row to cant said elements at an inclination from the vertical in simulation of clapboard.

4. An outer wall structure comprising a sheathing and a coveringoi fibre-cement siding elements applied in courses, battens secured to the sheathing in horizontal rows, the siding elements or each course having their upper edges secured to the sheathing adjacent to one row of battens and having their lower edges resting directly on the battens of the next lower row and overhanging and spaced outwardly from the upper edges of the '10 siding elements oi the next lower course.
